As many already know, studying for the physics GRE and getting accepted into a graduate program is not the final hurdle in your physics career.

There are many issues current physics graduate students face such as studying for their qualifier, deciding upon a field of research, choosing an advisor, being an effective teaching assistant, trying to have a social life, navigating department politics, dealing with stress, utilizing financial aid, etc.

Hello!I am an Italian student attending UCSB. I noticed that most of the fellowships (such us NSF) are only for US citizens or permanent residents.Do you know if there is any for international students?

It depends on what your research is. I am Canadian so I am also not eligible for NSF etc. The majority of international students I know apply to their home country for fellowships (I have a Canadian equivalent to the NSF). Another option in my field is the NASA Earth & Space Sciences Fellowship. It is the only one in my field that does not require American citizenship but you need to be working on a project that supports a NASA mission in some way.
